Spinal cord

ventricles, the 3rd and 4th ventricles, the cerebral aqueduct, and the central canal. Describe the purpose of the ventricular system. In your answer be certain to define components of this system that are more difficult the diagram; specifically Cerebral Spinal Fluid and Arachnoid granulations. (10 points) The ventricular system is made up of ventricles in the brain which contain CSF (Cerebrospinal fluid). The purpose of the ventricular system is to make and transport the CSF (Cerebrospinal…

like a cushion, dulling the force. Cerebrospinal fluid is one part of the extracellular of the central nervous system and it is a clear, transparent, bodily fluid that occupies the subarachnoid space and the ventricular system around the brain and spinal cord. The Cerebrospinal fluid is produced by choroid plex, which is a structure in the ventricles of the brain. The viscosity of the Cerebrospinal fluid is similar to the blood plasma. It produces approximately 500 ml each day and provides a…

syndrome causes complete paralysis with the exception of eye movement, however the patient is completely conscious and aware of surroundings (Pistoia et al., 2016). According to Pistoia et al., (2016), due to the disconnection of the cortex and spinal cord in…

Amyotrophic Lateral Sclerosis, more formally known as ALS or Lou Gehrig’s disease, is a neurodegenerative disease, causing the selective degeneration of both upper and lower motor neurons, as well as those in the motor cortex portion of the brain, which ultimately leads to the limited to complete loss of all voluntary muscle function. Now while the main pathology of ALS is the selective death of the previously mentioned motor neurons, more recent studies have suggested that the homeostatic…

could better the scientific understanding of SMA that could lead to a breakthrough in treatment that will strengthen infant’s bodies, extend life, and lead to a cure for their illness. Topic: Today, I am going to discuss a horrible disease, called Spinal Muscular Atrophy that plagues our children in the world today. Importance: This disease is the number one genetic cause of death in infants in America today. Credibility: I have been actively involved in fundraising money for research after…

and Symptoms ALS stands for Amyotrophic Lateral Sclerosis, also known as Lou Gehrig's disease. According to the ALS association they describe the disease as "a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord." This awful disease takes over from the outside in. The disease begins by affecting the body's voluntary muscles such as a person's arms or legs. Cramping and twitching of the muscles can occur as they begin to diminish. While the outer…

The five main parts of the brain are:- Midbrain, Pons Varolii, Medulla Oblongata, Cerebrum and Cerebellum The midbrain is forms part of the brainstem (along with the medulla oblongata and pons varolii). It is responsible for your level of consciousness. The midbrain consists of two stalk-like bans that come out from the base of the cerebrum and lead into the pons varolii. It contains both grey and white matter. The pons varolii is located just below the midbrain and is responsible for…

system, balance system, proprioceptors, and the brain. The visual system contains oculomotor neurons and eye muscles while the balance system contains semicircular canals, otolith organs, vestibular nerves and nuclei. The proprioceptors include the spinal cord, muscles, and joints in the body while the brain contains the cerebellum and cerebral cortex. All these components work together to maintain the human sense of balance in all individuals. When there is disconnect in any of these systems…

can be grouped together to form nerves, which are the primary organizational structures in one major branch of the nervous system, the peripheral nervous system. This is in contrast to the central nervous system, which consists of the brain and spinal cord. The peripheral nervous system can be sub divided into the somatic and autonomic nervous systems, the latter of which can be further sub divided into the sympathetic and parasympathetic nervous…

acidic protein (GFAP), cellular hypertrophy, and development of a pronounced stellate morphology (Lee et al., 2000; Liu et al., 2000; Messing and Brenner, 2003). Both beneficial and detrimental elements of astrogliosis have been described. In spinal cord injury (SCI), the stellate processes of astrocytes interdigitate to form a dense plexus that creates a physical and molecular barrier to nerve regeneration (Fitch and Silver, 2008; Ridet et al., 1997). Chronic demyelinated plaques in multiple…
